Heated copper metal reacts with oxygen to form the black copper oxide. The copper oxide can then react with the hydrogen gas to form the copper metal and water. When the funnel is removed from the hydrogen stream, the copper was still be warm enough to be oxidized by the air again.
"Concentrated nitric acid is a strong acid and a strongly oxidizing acid. Ingestion causes burning and corrosion of internal tissues." 1 If you spill concentrated nitric acid on your skin you should wash it off immediately with a large quantity of water. "Nitrogen dioxide forms acid on contact with moisture and is a poisonous, choking gas.
